FASTENER.

Elssugn Original application filed Apr112, 1917, Serial No. 159,139. Divided and this application filed August To all whom it may concern:

Be it known that I, GIDEON SUNDBACK, a subject of the King of Sweden, and resident of Meadville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Fasteners, of which the following is a specification. i This invention'relates to fasteners 'of the type wherein closures for the edges of a garment, curtain, bag, tent or the like are to be separably connected by a fastener which embodies a sliding operating device which separates the edges when moved in one direction and closes them when movedin the opposite direction. Hitherto in the use of such fasteners, the degree of"separation per mitted has been limited by xtlie fact the edges had to remain-joined atv at least one point. By a novel arrangement of parts,

involving the use of a flexible extension memher, I have made it possible to secure as wide an opening as may be desired. By reason of this advantage, my invention is particularly applicable to such articles as corsets, spats, curtains, etc., where w de separa tion without actual disconnection is required. This application is a division of my previous application for fastener, Serial 9 No. 159,139, filed A. ril 2, 1917, Patent No.

With'these an other objects in yiew, I have devised, the apparatus embodying my invention, as described in th following specification and illustrated in the accompanying drawing, of which Fig. 1 is a plan view of the device as ordinarily applied,

' 1 represents a body having edges 2 which 65 are to be closed. The fastener embodies stringers 3, 3 composed of tapes having corded edges 4, 4 to which the interlocking members 5 are clamped in staggered relation. A sliding hollow Y-shaped cam 6. fits over members 5 and travels along edges 2 to engage or disengag the interlocking members 5 on the respective edges 2. Cam 6 has slotted sides through which the tapes extend laterally but which retain members 5 against forces tending to separate edges 2. The tapes of stringers 3 are stitched respectively to the separate portions of body 1 beyond edges 2. One or both of the stringers 3 are provided'at the closing endwith stop mem bers 7 passing within the slider 6, and engaging the latter to prevent further movement. 7 Beyond the end of body 1 stringers 3 3 are extended to constitute extensions 8, and these extensions are connected at their outer ends by link members 9 joining the respective stringers. Extensions 8 are preferably provided with interlocking members 5, and are of such a length that when slider 6 is stopped by link members 9, the body 1 can be separated to such an extent that the extensions 8, owing to their flexibility, will straighten out end to end. In the fasteners as "heretofore used, without extensions, the

end members 9 would directly connect the.

lower end of body edges 2, and slider 6 would consequently not go the entire len h, thus preventing complete separation of e ges 2. By reason of extensions 8 receiving slider 6, as much openingmay be secured as desired, depending on the length of extensions 8. As the free edges of the extension 8 straighten out end to end, the maximum degree of separation of the lower edges of body 1 will be about twice the distance of the top of slider 6 from-the lower edges of body 2. In Fig. 3, the extension principle is ap- 'out requiring, complete opening. 10 is the usual lacing, and 11 is the fastener of this invention. The'body ofthe corset ends at 12,- and 13 are the extension members. When the slider is moved down to the lower portion of the extensions 13, these can stretch out end to end to such an extent as to per-i mit the corset to be stepped into or out of without complete separation, and when the slider is pulled up the corset will be quickly ,and firmly fastened.

In Fig. 4 is shown an application of the extension to a spat, in which 14 represents the body of the spat provided with the fas- Fig. 5 the strap is not split as in Fig. 4,

and only one stringer is connected thereto,

the strap also being sewed only to the body 14 on the side to which the stringer is attached. Thus the slider can go down to the lower end of the stringers as in Fig. 4, and the stringers will stretch out end to end so as to provide the wide opening. Inasmuch as the body of the spat 14 overlaps the free side of the strap, it makes no difference that the strap is not attached to the body on both sides.

In Fig. 7 the extension principle is applied to a curtain 17 carried by a body or support 18. such as a tent, automobile top, etc., and the stringer extension 19 is sufficiently long to permit curtain 17 to be swung around relatively to the support when separated. The other stringer exten- F sion appears as attached to body 18 for its entire length, but it may be partly free if desired. This arrangement is a decided advantage in enabling the curtain to be rolled u The locking means shown in-Figs. 8 and 9 comprises a plate 22 attached to the reinforcing loop 23 of the slider by means of the extensions 29, which are bent to lie within the loop 23 and serve as a pivot about which the plate 22 may be moved. The plate also has spring wings 24 which resiliently engage the ends of the slider channel when the plate 22 is swung downwardly from the position shown in Fig. 8 to that shown in Figs. 1 and 2. At this time the wings 24 close over the ends of the slider channels and obstruct passage of the stop members 7 as shown in Fig. 2. 25 is a slot in the plate 22 to increase its resiliency, and 26 are buttons or projections to furnish a finger hold. Une projection'26 fits into the slot 27 in the bottom of the slider. 28 is a fastening which secures the.

loop 23 to the doubled slider body. The slider can be positively actuated in either direction through the plate 22.

What I claim is: 1. In a body having meeting edges, means secured to and distributed along the length of said respective edges for connecting the verging channels,
